Testing is conducted at the Dartmouth Trace Element Analysis Core at the Center for Environmental Health Sciences at Dartmouth. Findings for both total arsenic and inorganic arsenic are reported.

The results to date have been a mixed bag with some cereals testing above the Codex Proposed Draft Maximum Level for Inorganic Arsenic in Polished Rice (200 ppb inorganic arsenic) and the maximum level that appears to be under consideration in the European Union for foods eaten by infants and young children (100 ppb inorganic arsenic).
